Last night’s collapse of part of the Big Dig in Boston does not look pretty. I used to drive through the new tunnels twice a day, and every time, when I saw the dripping of water from the ceilings and walls I wondered how long the massive tunnel would stay put. Concrete slabs that make up the ceiling fell and crushed a car, killing the driver. This could be a turning point for the over-budget and corruption-plagued Central Artery/Tunnel project. The former head of the Massachusetts Turnpike Authority said today, “I will not go into the tunnels with my family. I’d go in alone.” The Herald has a great blog on the subject.
